CAR- S EAT.

SPECIFICATION forming part of Letters Patent No. 724,610, dated April'7, 1903.V

Application filed July 28,1902. Serial No. 117,252. (No model.)

ful Improvements in Car-Seats, of which the,

following is a specification.

This invention relates to that class .of car seats or chairs in whichthe chair-back is made reversible; and the object of the presentimprovement is to provide a sim ple, durable, and efficient constructionand arrangement of the connecting mechanism between the reversiblechair-back and the stationary chair base or standard and in which suchconnecting mechanism has an arrangement and location whollybeneath thechair-seat proper without anyprojections beyond the same other than thesingle end-connecting ears by which attachment is had with therespective lower corners of the chair-back, such construction andarrangement affording within a given space Within a car a maximum,amount of seating-surface and, Vwhat is of equal if not greaterimportance,a free and unobstructed end access for the user osuchseating-surface, all as will hereinafter more fully appear and be moreparticularly pointed ont in the claims. v j

In the accompanying drawings, illustrative of the present invention,Figure 1 is an end elevation of a car seat or chair embodying thepresent improvements; Fig. 2, a fragmentary longitudinal ksection atline oc, Fig. 1, of one end of the'car seat or chair; Fig. 3, a planview with the chair-seat removed and illustrating the connectingmechanism be-` tween the chair base and back, the vertical attachingside ears or plates and one of the telescoping arms being shown insection; Fig. 4, a fragmentary elevation of the central portion of theconnecting mechanism; 'Fig'. 5, a detail end elevation of the same.

Similar numerals of reference indicate like parts in the differentviews.

Referring tothe drawings, 1 represents the stationary supporting base orstandard of the car seat or chair of any usual and snitable form.

2 is the seat proper of any usual form and construction and whichpreferably rests in `is supported in any usual manner on the base orstandard 1, either by the usual inclined tracks or by having a pivotalor rocking attachment thereto, as shown in Fig. l, and in which thepivotal movement is had by means of the longitudinal tie-rod 4 passingthrough adjacent pivot-hubs on the respective parts and the rockingmovement confined Within the prescribed limits by separated ears 5 onthe seat-frame adapted to have limited movement withY relation to hubson the main base, in which the secondary tie-rod 6 of such base issecurely fastened.

7 is the chair or seat back of any usual form and which in the presentconstruction is provided with depending extensions or bars 8 at itsrespective lower corners for attachment to the carrying or supportingmechansm hereinafter described.

9 is a pivot-block secured centrally upon the main base l in any usualmanner, preferably by being clamped onto the longitudinal tie-rod 4 ofsuch main base. Y

' l0 10 are companion pivot-studs havingseparated relation on the uppersurface of the pivot-block9. Y ll 1l are horizontally-arrangedcounterpart arms journaled by suitable journal-eyes at their ends uponthe pivot-studs 10 10 aforesaid, and such ends are operatively connectedtogether to move in unison by toothed sector formations 12 12 on therespective parts or by any other usual and equivalent means ofconnection.

13 13 are extensions of the arms 1l 11 and are connected thereto topermit of a sliding or telescoping movement of the one upon the other inthe practical operation of the mechanism. A very simple slidingattachment of the parts is illustrated in Fig. 3 of the drawings,inwhich one part is shown as having a tubular form, in the bore of whichthe straight shank of the other part is adapted to have sliding movementin a direct manner and without any lateral play. A

14. represents vertical bolts affording a substantial connection betweenthe outer ends of the extensions 11 aforesaid and the dependingextensions or bars 7 of the chair-back and in a manner to permit of theoscillation of such IOO 'the chair-back 7, carried by the same.

16 represents cam-slots or grooves formed in the end portions of theseat-carrying frame 3 or in separate plates lixedly attached thereto.

17 represents studs or projections on the extensions 13 of the arms 11,adapted for engagement with the cam-slots 16, as shown, the arrangementand formation of parts being such that with a vibration of the arms 11from one edge of the seat to the other the outer ends thereof will becaused to move in rectilinear paths parallel with the respective ends ofthe seat.

18 represents depending headed studs on the under surface of theextensions 13 of the arms 11, but which may be located upon any adjacentpart of the mechanism having movement in unison'with said armextensions.

19 represents fixed horizontal webs or projections upon the stationarybase 1 or other like fixed part of the chair or seat of the car andwhich are located in separated relation at the respective limit of themovements of the outer parts of the carrying-arms 11 and adapted to haveholding engagement therewith, so as to hold the seat-frame, seatportion, the., at the proper degree of inclination after a reversal ofthe chair-back has been effected. To this end the said webs orprojections are provided with open-ended slots 20, as shown in Fig. 3,into which the shank portions of the headed studs 18 enter, with theheads thereof beneath the body portion of said web, to attain a positiveengagement of the parts and a consequent locking of the chair-seat atthe desired degree of inclination.
